1 Claim.

The object of the present invention is to produce a compound sheet material of improved character suitable for many'industrial purposes where a distinctive appearance is of importance combined with good protective qualities.

With this object in view, compound material according to the invention is characterized by a base layer of paper, cardboard, or the like, tin and other metals and wood and other hard materials as well as fabrics or substances of soft or pliable character, with a facing, layer or lining in the form of a transparent cellulosic or equivalent film united to the base layer by fine lines of adhesive which are continuousand intersect.

In this way totally isolated areas free of adhesive are distributed over the entire opposed surfaces of the base layer and film, the lines which bound these areas extending in various directions so thatno matter how ,a sheet is bent or out no continuous edges can exist devoid of adhesive such as is found in compound materials united by stripes, dots or discontinuous patches of adhesive whereof various examples are known. It has already been proposed to cover, line or face sheet material with films of material known by the trade name Cellophane, or the like, in various ways as by spraying the same in liquid form or by uniformly applying an adhesive or solvent uniformly to one of the two surfaces to be united, but the result has not been satisfactory. The methods of shape, dot or discontinuous gluing referred to, although more or less satisfactory where certain materials are concerned, are not suitable for uniting a film such,

as Cellophane to material such as cardboard, because of the tendency of the film to curl, unless precautions aretaken to bind the margins or edges. By means of the present invention all disadvantages are overcome and in addition a new manufacturing product is obtainable, having,

a patterned effect due to the lines of adhesive beins visible through the film.

and outwards upon the'creases c. The reference d represents the facing of transparent or translucent material which constitutes the lining for the base a, and e denotes the lines of adhesive applied to the base to eifect a union between the two. Although the lines are here shown to be straight, it will be understood, from what has been said before, that the lines need not be straight but may be of any shape, so long as a pattern is produced with continuous lines which intersect. The adhesive may of course be coloured to contrast with the colour of the base layer of material and with that of the transparent film if the latter is itself coloured.

Material according to the invention is particularly applicable for the making of boxes of various kinds or decorative purposes.

I claim: Y

A compound decorative sheet material characterized by a base layer and a facing thereon of a transparent cellulosic film united to the base layer byfine lines of adhesive which are continuous and intersect in a crosswise relation, whereby totally isolated areas larger and of greater extent than said lines and free of adhesive are distributed over the entire opposed surfaces of the base layer and film, the lines which bound these areas extending in various directions in the formation of a design of reticu-' lated character and so that no continuous edges I can exist devoid of adhesion; and being visible through the film with a background effect contrasting distinctly from that of said areas so as to impart an attractive appearance to the resultant material.
